Is fear driving the anti-vaccine movement?May 22, 2019Vaccines are one of the most effective means for preventing disease ever developed and one of the great triumphs of scientific medicine. Widespread vaccination of children has dramatically reduced—and in some cases eliminated—infectious diseases that have plagued humanity for thousands of years. There is less research evidence for the impact of vaccination in companion animals, but there is ample reason to believe vaccines have been equally successful in dogs and cats.3–7 Any veterinarian old enough to remember the emergence of canine parvovirus (CPV) in the U.S. in the late 1970s, for example, would probably testify to the efficacy of vaccination in reducing the incidence of this disease.5–7 There also is compelling evidence showing the reduction of both canine and human rabies cases due to vaccination programs aimed at dogs.8–12 And similar to smallpox, the veterinary disease rinderpest was eradicated largely due to the use of an effective vaccine.13 Vaccines and autism Despite the evident success of vaccination in reducing morbidity and mortality, there has always been controversy about the practice.14 The introduction of widespread vaccination in children was initially met with resistance and legal challenges. There was fear about the safety of vaccines, as well as resistance rooted in …
Is banning "artificial" ingredients based on fear or science?March 1, 2019Since the late 1980s, individuals and organizations have been trying to warn the public about a deadly chemical known as dihydrogen monoxide (DHMO). Though widely used in the home and in commercial settings, including the health-care industry, this substance has been shown to cause severe lung damage and even death when inhaled in small quantities. Hundreds of thousands of people die annually from this cause.1 DHMO also can produce electrolyte disturbances and potentially fatal neurologic symptoms when taken orally, and it can cause severe burns and even explosions when heated.2 A number of surveys have found high levels of support for banning DHMO, and elected officials in several countries have explored taking such action, although DHMO remains ubiquitous.3,4 Given the obvious dangers of this chemical, why do public health agencies not take action to restrict it? It is possible that funding and political influence from industry impede regulatory action. However, it is more likely that governments have chosen not to ban DHMO because it is essential for life. Most people are surprised to learn this until they recognize the nontechnical name for this chemical—water. Is "chemical" a dirty word? The campaign against DHMO has been used as a humorous …
Is there a gold-standard test for adverse food reactions?February 14, 2019Some of the most common conditions seen in small-animal practice are gastrointestinal complaints, such as vomiting and diarrhea, and skin problems, including pruritis.1 Among the many differential diagnoses for these symptoms are adverse food reactions (AFRs).
Debating raw dietsJanuary 2, 2019In spite of resistance from most veterinarians and from public health authorities, the popularity of raw meat-based diets for dogs and cats continues to grow.
What is screening and is it beneficial?November 30, 2018Screening is the use of diagnostic tests in apparently healthy individuals with no clinical symptoms.1-2 Its purpose is to detect asymptomatic disease with the presumption that this can allow earlier, more effective intervention and will reduce suffering and delay or prevent death.
Assessing claims of vaccine-induced ITP, IMHAAugust 29, 2018The use of any medical interventions involves balancing risks and benefits. A treatment that has zero risks almost certainly does nothing meaningful. In the case of vaccination, the benefits are well established and often taken for granted. Many serious, even life-threatening, diseases can be prevented through vaccination. In humans, childhood vaccination is recognized as the No. 1 public health achievement of the 20th century,1 and the benefits continue to grow in the 21st.2 Although less data is available in veterinary medicine, there is no question that vaccines have been enormously effective in reducing illness and death in veterinary species as well.3-4
Uses, evidence, and safety of laser therapyAugust 16, 2018At its simplest, laser therapy is the application of light to living organisms to improve health. However, great detail exists behind this simple idea. The wavelength and power of the laser, the location and duration of exposure, the number of treatments, and many other variables are crucial to the effects achieved.
What is a placebo?July 10, 2018There is no consensus definition of a placebo or of the placebo effect. It is generally accepted that a placebo is an inert treatment with no direct physiologic effect on a patient’s disease or symptoms. Placebo effects, then, are effects associated with the administration of an inert treatment that are perceived as beneficial by the patient or that of observers.
Evidence-based medicine is key in achieving an ethical clinical practiceApril 17, 2018The relationship between evidence-based medicine (EBM) and ethics may not be immediately apparent. EBM focuses on facts and data, safety and efficacy, and determining what we do and don’t know. Veterinary ethics is about doing what is right or wrong in the context of veterinary practice.
